Paired box gene 8, commonly known by the abbreviation PAX8, is a commonly used immunostain in gynecologic pathology and genitourinary pathology.
Tumours with positive staining
- Thyroid tumours ~ 90%.[1]
- Renal cell carcinomas ~ 90%.[1]
- Renal oncocytomas ~ 80%.[1]
- High-grade ovarian serous carcinomas ~ 99%.[1]
- Nonserous epithelial ovarian neoplasms ~ 70%.[1]
- Endometrial carcinomas ~ 98%.[1]
- Pancreatic neuroendocrine tumour.[2]
- Can help differentiate from lung NETs.
Negative staining
